A temperature sensor is also set up on converter.
10. a kind of continuous type piston type squeezes out the application method of ejecting device, which is characterized in that including following step
Suddenly：
In the initial state, printing consumables is filled in left barrel, left seal cover board is located at the top of left barrel, the left slider
Discharge port is opened, feed inlet is closed；Without printing consumables in right barrel, right seal cover board is located at the bottom of right barrel, right sliding block
Discharge port is closed, feed inlet is opened；
The first step, after consumptive material is heated to thermophilic by left heating plate, the first driving motor rotates forward, and left feed screw nut is with left sealing
Cover board moves down, and consumptive material discharge port through left slider under the extruding of the left seal cover board is extruded from nozzle；At the same time,
Under the reverse drive of the driving gear and driven gear, right leading screw reversion, right seal cover board follows right feed screw nut to increase,
Right feed pipe by being connect with the feed inlet of right barrel sets right hopper until the umber of pulse of the first driving motor reaches
Definite value；
Second step, after the umber of pulse of the first driving motor reaches preset value, pulse number zero；Second driving motor is just
Turn, rack moves to left, and right spring generates rebound, is moved after right sliding block, and the feed inlet of right sliding block is closed, discharge port is opened, and left spring
It is pressurized, the feed inlet of left slider Forward, the left slider is opened, and the discharge port of the left slider is closed；
Third walks, and after consumptive material is heated to thermophilic by right heating plate, the first driving motor reversion, left seal cover board increases, by with
The left feed pipe of the feed inlet connection of left barrel is to the left hopper, at the same time, in driving gear and driven gear
Under reverse drive, right leading screw rotates forward, and printing consumables is under the extruding of right seal cover board, via the discharge port of right sliding block from nozzle
It is extruded, until pulse number reaches preset value；
4th step, after the pulse number of the first driving motor reaches preset value, pulse number is zeroed, and the second driving motor is anti-
Turn, rack moves to right, left spring rebound, is moved after left slider, the feed inlet of the left slider is closed, and discharge port is opened；Right spring by
Pressure, right sliding block Forward, the feed inlet of the right sliding block are opened, and the discharge port of the right sliding block is closed；
Above four steps constantly repeat, and realize the continuous printing of pastes.
